This register reflects (reads back) the value set in the MODSET register. A valid OEM password is required for access to this
register.

Byte Address
This register reflects (reads back) the status of the bits corresponding to the parameters defined below. A valid OEM password
is required for access to this register. Otherwise, reads are undefined and writes are ignored.

This register works in conjunction with the LOSFLT register to control the operation of the loss of signal comparator. The
comparator’s output, RXLOS, is asserted when the input on VRX falls below the level in LOSFLT. The output will then be de-
asserted when the VRX signal rises above LOSFLTn. The input signal is subject to scaling by the RXPOT. If the LOS
comparator is disabled, i.e., LOSDIS = 1, this register is ignored. A valid OEM password is required for access to this register.
This register is non-volatile and will be maintained through power and reset cycles.
